title: Optimizing single port surgery: a case report and review of technique in colon resection.
abstract: BACKGROUND
  Minimally invasive colon surgery was first described in the early 1990s, decreasing the morbidity compared with open procedures. Recently, single port laparoscopy has emerged, with reports of applications to colon surgery. Although feasible, many new technical challenges exist.
  
  
  METHODS
  An optimal operative technique for colon resection entirely through the umbilicus, using a robot and a GelPort is described.
  
  
  RESULTS
  The robotic advantages of visualization and articulation minimize the disadvantages of single incision surgery. Programming the robotic arms in reverse decreases instrument clashing. In addition, the GelPort allows for trocar spacing and freedom of placement while providing a wound protector for specimen extraction.
  
  
  CONCLUSIONS
  As single port surgery develops, disadvantages must be overcome. Using a combination of the robot and GelPort, these disadvantages are addressed and minimized.
